agpgart: X tried to set rate=x0. - Page 2

**zander** · 11-07-05, 11:29 AM

Please give the attached patch a try; it makes sure the NVIDIA Linux graphics driver won't set the reserved bit 2 in the mode passed back to AGPGART, even if it's present in the the AGP info structure filled in by AGPGART, and makes the NVreg_ReqAGPRate NVIDIA kernel module parameter AGP 3.x aware.

# sh /path/to/NVIDIA-Linux-x86-1.0-7676-pkg0.run --extract-only
# cd NVIDIA-Linux-x86-1.0-7676-pkg0
# patch -p0 < /path/to/NVIDIA_kernel-1.0-7676-1404254.diff.txt
# ./nvidia-installer -n

but the driver is the 7676 pkg1 (is this patch not included in that release?)
agpgart: Detected NVIDIA nForce2 chipset
agpgart: AGP aperture is 256M @ 0xc0000000
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: reserved bits set in mode 0x1f00020c. Fixed.
agpgart: X tried to set rate=x0. Setting to AGP3 x4 mode.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 4x mode
